Application August 10,1931, Serial No. 556,288 Renewed September 15,1933 2 claims. (cl. fia-'1175) This invention relates generally to.extension tables, more speciically to a slide construction wherebycompanion sections of the top will be simultaneously moved an equaldistance in opposite directions by pulling or pushing on either section.f

The principal object of the present invention is to provide a slideconstruction for the purpose described which will occupy and operate inbut little space, yet permit a wide separation of the companion sectionsof the vtable top.

Brieiiy stated, the invention consists of a base rail upon which isslidably mounted a pair of oppositelydisposed slide bars. A lever ispivoted midway of its ends to the rail; the opposite ends of said leverbeing connected to the slide bars by links` to which are connected asecondary lor auxiliary lever disposed parallel to said pivoted lever.

Other objects and advantages will be apparent from the followingdescription, reference be-A ing had to the accompanying drawings, inwhich; Fig. l is a bottom plan View of the extension table with the topsections in closed position.

, Fig. 2 is a section taken on line 2-2 of Fig. l in the directionindicated by the arrows.

Fig. 3 is a section taken on line 3-3 of Fig. 1. Figs. 4, 5, .6, and 7are fragmentary bottom plan views showing various positions assumed bythe working parts 0i the improved slide construction during opening ofthe table top sections.

Referring more speciiically tothe drawings, 10 and l1 designate end andside strips respectivelyof a table frame 13 upon which is mounted a top14 formed of companionsections 15 and 16, the frame being supported inthe usual manner by legs 17.

The slide constructions generally designated at v18 and 19 are suitablyspaced apart and .iounted in the frame `in parallel relation.

Slide constructions are of exactly the same construction, each of whichinclude a base raill 20 extending between and secured to the endstripsvlO. y

, Mounted on each side of the kbase'rail 20 are slide bars 22 and 23which in turn are secured by screws'or the like 24 to the underside cithe companion sections 15 and 16 of the table top. In the presentinstance, slide bar 272 is secured tosection 15, whilebar 23 is securedto section 16. -The slide bars are provided with tongues 24 whichslidably engage grooves or guideways formed in the side faces of thebase rail.

A lever 26 is pivoted midway of its ends on a pin or the like 27 to theunderside ofthe base rail, the pin lbeing preferably located at a pointhalf way between the end and side faces of said base rail. M.

Pivotally connected to slide bars 22 and 23 rey spectively by Vscrews orthe like 28 and'29 are 60 links 30 and 31, which in turn are connectedby pivot pins 32 and 33 to the opposite ends of lever 26. Link 30'extends beyond pin 32, and is `connected in a like manner, as indicatedat 34, to one end of an auxiliary link or bar 35, the opposite end ofwhich is connected to link 31 at a point indicated at 36 between pin 33and its piv` otal connection 29 to slide bar 23. v

Auxiliary link 35 is disposed in parallel relation to lever 26, andserves to permit a wider separation or extension of the top sectionsthanv would be possible with a single pivoted lever of the-same relativesize.

Assuming that the top sections are being opened or extended, lever 26turns'on pivot 27 75 through links 30 and 31 from theposition showninFig. 1 to that shown in Figs. 4 and 5.

During the above interval, the lever 26 and links 30 and 3l serve tomove the sections.

Auxiliary link 35 now coacts vwith the lever 26 to g@ -move the sectionsfrom the position shown in Fig. 6 to fully open position as shown inFig. '7. From the foregoing, it will be readily seen that when either ofthe top sections 15 or 16 are manually moved the opposite sections willmove a corresponding distance in the opposite direction.

I claim: f' l 1. A slide construction of the character de- 9@ scribedcomprising a rail, a pair of slide bars slidably mounted 'on each sideof said rail, a lever When separated, one or more loose leaves maypivotally mounted midway of its ends on said rail, a link pivotallyconnected to each of said slide bars and to the outer ends of saidlever,

and an auxiliary link connected to said links in parallel relation tosaid lever.

2. A slide construction ofthe character .de-

scribed comprising a rail, a pair of slide Ybars slidably mounted oneach side of said rail, a lever pivlite otally mounted midway of itsends on said rail, a link yconnected to said lever adjacent one endthereof and to one of said slide bars, asecond link connected to theother of said slide bars and to the opposite end of said lever, and anauxiliary link connected` to the outer end of said rst link andA nectionto said lever and slide bar.
